To refactor CSS architecture for a large project, audit your current setup and implement a modular, token-driven structure. Applying methodologies like ITCSS, BEM, or SMACSS organizes styles hierarchically, ensuring maintainable and scalable design systems across frontend teams.

CSS design-token driven theming centralizes styling decisions into reusable variables for colors, typography, and spacing. This approach ensures consistent UI across components, supports dark mode, and simplifies theming across large applications by maintaining a single source of truth.

Ensure accessibility and WCAG compliance in CSS design systems by implementing tokens that enforce WCAG-compliant color contrasts. Building accessible components with semantic HTML and ARIA attributes alongside your CSS ensures usable interfaces for all users.

CSS-in-JS can complement ITCSS or SMACSS patterns by applying their architectural principles within component-based frameworks. While ITCSS and SMACSS organize global stylesheets, CSS-in-JS practices can enforce scoped styling and token-driven theming at the component level for large product apps.

The best way to implement responsive design using container queries is combining them with advanced grid and flex layouts. This approach allows components to respond to their parent container size rather than the viewport, creating modular and flexible UI components.

Frontend teams should use design tokens for cross-browser styling because they provide a single source of truth for UI attributes. This token-driven modular CSS structure accelerates feature delivery, improves design consistency, and simplifies responsive layouts and dark mode implementation.
